Results of three-year investigation of blue lupine (Lupinus angustifolius) of Mirtan variety response to the different terms of sowing in monocropping and mixed crops sowing conditions of the Republic of Belarus were presented. In the central area of Belarus under monocenosis and binary mixtures since the early April sowing terms till the late ones (the first decade of June) the increasing of daily average temperature caused the acceleration of the linear growth, growing of herbage and the reduction of the interphase periods of sprouting- budding and sprouting-flowering as well as the prolonged period of the stage of flowering-grey mould bean. In the binary mixtures of lupine with oat (Avena) and triticale the competitive ability of cereals declined from the early till the late sowing terms while the competitive ability of beans increased. As a result, the amount of beans in the fresh yield increased from 48-49% up to 68-75%. It was established that blue lupine of Mirtan variety in monocropping and mixed sowing conditions with oat and spring triticale under conditions of different sowing terms from the third decade of April till the first decade of June at the stage of bean flowering showed the yielding capacity of herbage of 236-317 c/ha, of dry matter – 37,5-48,4 c/ha, at the stage of grey mould bean – 288-429 and 62,0-79,4 c/ha, respectively
